Microsoft says a Microsoft 365 Copilot bug has been causing the AI assistant to summarize confidential emails since late January, bypassing data loss prevention (DLP) policies that organizations rely on to protect sensitive information.
For some reason it hasn’t put out a security advisory - but instead buried it in a service alert which isn’t publicly visible.

@GossiTheDog yeah a "BUG"
@lexinova @GossiTheDog confidential information has definitely leaked. Us peasants were not supposed to know what MS does with our data.

@GossiTheDog yeah a "BUG"
@lexinova a bug. As in a digital "listening" device planted by Microslop for (at least the) US police/authorities to hoover up all that juicy confidential data somewhere else.

So the AI assistant designed to help you write documents is now deleting your documents
At some point we need to ask: are we adding AI because it solves a problem, or because someone in a boardroom decided every product needs an AI checkbox for the next earnings call
This is what happens when you ship features to impress investors instead of users

@GossiTheDog while generating summaries might be a benefit. Why delete the original mail? How can one implement such a feature so lousy? (rhetorical question)

"Bug", "Code error", exposing sensitive data. Yeah, nah. I'm sure that's it. Who got the data? Microslop? Gargle? Whose hands did it end up in? Hmmm.
